comment inserer de l'audio dans mon applet ?
salut a tous
J'ai un applet qui fait rebondir une balle et je voudrais y faire activer un son a chaque fois que la balle rebondi, mais je sais pas comment quel type d'audio java peut lire , comment l' implementer dans mon code.
toute aide me sera utile merci beaucoup
voici le code :

fadeMover.stop();
